Specification of Letters Patent.

Patented Feb. 19, 1907.

To all 'ru/1,0771, 2515 Tftrtg/ concern.-

Beit known that we, WILLIAM A. HARRIS and BENJAMIN S. H. HARRIS,citizens of the United States, and residents of Greenville, in thecounty of Greenville and State cf South Carolina, have invented certainnew and useful Improvements in Pneumatic IVater-Lifts, of which thefollowing is a specification.

This invention is an improvement in pneumatic water-lifts, and has foran object to provide a novel construction by which the water may beelevated by pneumatic pressure and which may be utilized as afire-extinguisher when so desired and the invention consists in certainnovel constructions and combinations of parts, as will be hereinafterdescribed and claimed.

In the drawing the figure is a side elevation, partly in section, of anapparatus embodying our invention.

In carrying out the invention we provide in the well cr other source cfwater-supply a tank P, having a water-inlet controlled by a strainer Rand an inwardly-opening checkvalve Q. This tank is provided at its upperend with stay-bars O, pivoted at their inner ends to the tank andarranged at their outer ends to bear against the wall cf the well, andthus brace the tank in position. An air-pipe B and a water-pipe Dconnect with the tank and extend upwardly therefrom, the Waterpipeprojecting down into the tank, as shown, and being provided a shortdistance above the tank with the upwardly-opening check-valve N. Thispipe D extends above the floor or ground line and is provided with adischarge-pipe having a faucet J and above the said pipe and faucet witha stop-cock E and is provided above the stop-cock E with a branch D',extending to and opening into the water tank or reservoir S. By a propermanipulation of the valves and stop-cocks and the operation of the pump,presently described, water may be forced from the lower or supply tankinto the upper or reservoir tank or be dispensed therefrom, as may bedesired. The reservoir-tank S is also provided with allot-water pipe K',provided with a faucet K, and suitable means at l and 2 may be providedfor heating the water in the reservcir S, and a discharge-pipe M',having a faucet or valve M, may be utilized in connection with a hose M2for use as a fire-ex- I tinguisher, as will be understood from thel ldrawing. 4 the upper through a suitable T, with a branch pipe D2, havingan emergency-valve G and united by a couplingD3 with the branch pipe B2cf the air-pipe B, leading to the upper end cf a purifier or filter Fand also with the upper end of the air-pipe B, such pipe B beingsupplied with an intermediate valve H. The purifier i is in the form ofa tank adapted to held water and is provided with a discharge-pipe L',having a faucet L, the several faucets J, K, and L being preferablyarranged in close proximity and arranged to discharge to the same sink,as shown, and the purifier is normally supplied with water lto a levelslightly below the connection of the pipe L' therewith. This purifier Fhas the discharge-pipe F' supplied with the valve T, and to thisdischarge-pipe above the valve T We connect the pump discharge-pipe B',having a checkvalve C, opening toward the filter and arranged to besupplied with air from the pump A. This pump is suitably constructed forVcompressing air, and the air is forced from the pump through theair-filtering apparatus to the desired peint. Normally the welltank P isfilled with water, which passes in through the strainer R andcheck-valve Q. Before the pump is operated the filter F should be filledabout half-full of water. This may be accomplished by removing the plugU. The purpose of the filter is to cool and cleanse the air before itpasses through the air-pipe B into the well-tank P. This pump must beoiled in order to be successfully used, and as the air heats when beingy compressed it is important to remove the effects cf grease and heat,and for this reason we employ the filter, as without the filter the airwould pass directly from the pump to the l well-tank, carrying with itthe bad effects of oil and heat.

In order to fill the Water-reservoir S the drain-cock T, emergency-valveG, and faucets J, L, and M should be closed. The intermediate valve H,stop-cock E, and faucet I K should be open, and the pump A shot ld be loperated to force air thror gh the pipe B' and g' check-valve C thror ghthe water in the filter |l F and air-pipe B to the well-tank, the pres-I sure of the air forcing the Water through the The branch pipe D', aswell as end cf the pipe D, communicates,

facuet K, and when the tank S is full the water will flow out of thefaucet K, indicating that the tank is ull, and such faucet can then beclosed. When the well-tank P has been emptied in order to permit it tofill through the strainer R and check-valve Q, the exhaust-valve Lshould be opened, which permits the air to escape and pass out as thewater runs into the tank. The system is now charged with water.

In order to get fresh water directly from the well, the drain-cock T,emergency-valve Gr, stop-cock E, and exhaust-valve L should be closed.The faucet J should be opened, and the pump should be operated to forceair into the tank P, which will cause the water to flow out of thefaucet J. After a portionsay one-fourth-of the water has been forced outof the water-tank P the space in the tank can be used as a storage forair, and by pumping up pressure water can be had to the extent of theexcess of pressure without pumpin. 2iVhen the tank S is used for hotWater, the 'operation will be the same as before deas the forcing ofcold wa- Swill force out hot or through the scribed for filling, vterinto the tank cold water, as the case may be, faucet K.

In case of fire a hose may be attached to the faucet M. The stop-cockEand intermediate valve H should be closed, the emergency-valve G andfaucet M opened, and the pump operated to quickly raise the pressure inthe tank S to a sufficient extent to throw water on top of any ordinaryhouse. Tf the water in the tank S should be exhausted before theordinary results are accomplished, the faucet M may be closed, the hoseremoved and connected with the faucet J, the intermediate valve H andfaucet J opened, leaving the emergency-valve G open, so as to get thebenefit of pressure in the tank S, and the pump be operated to force-thewater out of the faucet J and the hose M2 applied thereto. Lawns andgardens may be watered in like manner.

The water in the filter should be changed as often as necessary toinsure pure air. This can be readily done when about one-fourth of thewater is out of the well-tank P by pumping up the pressure higher thanfor ordinary purposes, when the intermediate valve H may be closed, thevalves L and T opened, and when all the water in the filter has passedout through the drain-cock T such cock should be closed and theemergency-valve and stop-cock E opened, permitting cold water to runinto the filter I" until it is filled sufficiently,

intermediate valve H may now lmay be caused to flow with which will beindicated by water 1 running out at the exhaust-valve L. The l leadingand the system will be ready for use, as before.

drained out of the filter by opening the draincock T, which shouldremain open over night. Then before again using the drain-cock T shouldbe closed, the plug U removed, the exhaust-valve L opened, and watershould be poured in until it runs out of exhaust-valve L, when the plugU may be replaced, the exhaust-valve L closed, and all will be ready foruse. It will be understood that the tank can only be used for hot waterwhen connected to a stove or range or other heating appliance inthewell-known manner. When the tank S is used for cold water only, theconnections l and 2 may be plugged.

The check-valve N, it will be understood, is placed in the water-pipe Dto prevent water from passing back into the well-tank P.

It will be noticed in the improved system as described the air isdirectly supplied .to the water the well or other supply through thefilter, which cleanses it, and the water a few strokes of the pump.

The check-valve C in the pump dischargepipe prevents water from passingfrom the filter F back into the pump. Except for this check it will benoticed that a small leak in the pump will permit the water in thefilter to ease back into the pump, which would be objectionable.
